desired.

Riders 5 are mounted for reciprocation on the and InWerdly p l e g bolts 32 are secured tracks 4. In oppositely disposed riders 5, a scale to e latch rings 39 and are mounted for Sliding rod 6 is mounted for longitudinal adjustment, movement in the sockets 2|. The inner ends of but when the scale rods have been adjusted endthe latch bolts 32 are adapted-to be received in Wise, they are held in place by set screws 1 seats 34 formed in the plungers 22. The latch threaded into the riders 5. rings 30 may be shifted, against the action of the Carriages 8 are mounted to move along the return springs 3|, to disengage the inner ends of tracks 4. The carriage 8 is a composite structhe latch bolts 32 from the seats 34, the latch 55 rings 30 being supplied with outstanding finger pieces 33, for that purpose.

In that end of each plunger 22 which is adjacent to the base I, there is formed a T-shaped slot 35, extended entirely through the plunger 22. Into the slot 35, may be slipped crosswise, the T-shaped shank 36 of a disk-like foot 31, whereon a cutter 38 is mounted for rotation. Owing to the T-shape of the slot 35, and the corresponding shape of the shank 36, the cutter 38 cannot turn about the axis of the plunger 22 and the cutter 38 always will track properly along the plate 2 of glass. In order to prevent the shank 36 of the cutter-carrying foot 3'! from sliding crosswise out of the slot 35, a collar 39 is slidably mounted on the plunger 22 and may be slid down, into engagement with the foot 31, to assume the position delineated in Fig. 8 of the drawings.

The scale rods 6 can be adjusted lengthwise in the riders 5 and be held in adjusted positions by the set screws 1'. The scale rods 6 and the riders 5 may be moved lengthwise of the track 4 and the mechanism shown in Fig. 4 can be shifted lengthwise of the support IS, the cutters 38 being placed according to the graduations on the scale rods 6, to regulate the width of the strip of glass which is to be cut. By means of the grip I! or any other appropriate instrumentality, the carriages 8 and the support [6 may be slid lengthwise of the tracks 4, the cutters 38 cooperating with the plate 2 of glass, to cut ofi one or more strips of glass, of different widths.

The springs 26 urge the cutters 38 to the glass 2. In the event that there is no plate of glass on the base I, the movement of the plungers 22 is stopped by engagement between the collars 21 and the sockets 2 I.

In the event that it is desired to hold the cutters 38 in spaced relation to the base I, the latch collars 30 may be moved transversely of the sockets 2f, by means of the handles 33, the latch bolts being engaged with the seats 34 of the plungers 22, after the plungers have been raised from the position of Fig. 4 to the position of Fig. 5.

The device is simple in construction, but will be found thoroughly advantageous for the ends in view, it being possible to bring about an accurate cutting of a plate of glass, to such dimensions as occasion may require.

What is claimed is:

In a machine for cutting glass plate, a base, tracks carried by the base, carriages mounted to move longitudinally of the tracks, a support extended between the carriages and disposed transversely of vthe tracks, a glass cutter; positioning means for the glass cutter, embodying riders mounted to move along the tracks, and a calibrated rod disposed transversely of the tracks and carried by the riders; and means for mounting the glass cutter for adjustment longitudinally of the support, whereby the working position of the cutter may be determined by reference to the calibrations of the rod, when the positioning means is moved to a place adjacent to the sup-' port, the positioning means being movable to a place remote from the support, and. then constituting a stop which, forming an abutment for the mounting means, limits the stroke of the cutter with respect to the glass plate to be cut.
